To all whom it may concern: 1 v I Be'it known that I, CLINTON C. BUTLER, a citizen of the United States of America, and a resident of WVat-erloo, Blackhaiwk county, Iowa, have invented certain new and useful Improvements in Gas-Producers for Explosive-Engines, of which-thefollowing is a specification.- v My invention relates to improvements ingas-producers for internal-combustion "en-- bustion from kerosene or the heavier" pe .troleum products, such means being'so 10-.

cated and associated with the combustionand the lnlet-port of the combustion-chamchamber of an engine as to borrow heat'by conduction and radiation therefrom, to act "conveniently and without loss of energy, and with a maximum efliciency. This-object I have accomplished by the means which are hereinafter described and claimed, and which are illustrated in the accompany ng drawings, in which:

Figure 1 is a -horizontal central section of the combustion-chamber part of the cylinder of an explosive-engine and of'my auxiliary gas-producer chamber, its valve and the communications between it and said combustion-chamber. Fig. 2 is an elevation of the end of said gas-producer chamber as mounted on said combustion-chamber; Fig. 3 is a detail view of the interior of a gasproducer chamber of a variant form, with the head removed, and parts broken away.

Similar numerals of reference denote cor-- responding parts throughout the several VIEWS.

- The engine-cylinder 1 is represented as being horizdntaL-containing a piston 2, and its combustion-chamber 3 is provided with both inletand exhaust-ports, closed by means of the resiliency-controlled inletand exhaust-valves 16 and 18 respectively. The combustion-chamber also contains a sparkplug 21. The exhaust-valve 18 is actuated by any suitable means at proper times, to exhaustthe burned gases from said combustion-chamber into the outlet-chamber 20. The inlet-valve 16 is actuated on the suction' stroke of the piston 2 in the usual way.

common passage 17 intervenes between the combustion-chamber and the inletand exhaust-ports. The cylinder-head i is formed to cooperate in use with an auxiliary spaced Specification of Letters Patent.

head 9,'se'cured detachably thereto, and is secured by bolts and nuts 2223. As shown in Fig. 1, both said heads have spaced vertical ribs, 5 and. 8-respectively, which, however, are alternatedjn such a fashion asto permit the ribs on each head to lie between and spaced from the ribs onthe other head to provide a zigzag passage 11 therebetween,

unmterruptedly from an inlet-tube 10 to an ing 14 of a rock-valve 13 when the latter has been rocked to open into said chamber,

bustion-chamber when the valve 1 6 is moved to open said inlet-port, which prevents a backward escape of gas into the passage 11,

since the said valves must be alternately moved to fulfil this function.

The inlet-tube 10 is in communication sons and gasolene, with the communicawith a carbu'reter not shown, which has supply-pipes to separate reservoirs of kero- 'tion controlled by a suitable valve adapted to permit either fluid to be used. The starting; of the engine is efiectedwhen the gasolens has been first supplied to the carbureter Way by way of the chamber 19 and inletport past its'valve 16 to the combustionchamber 3. After the engine is thus started by the use of gasolene the gasolene is shut oil from the carbureter and Kerosene introduced'therein. The dense, relatively heavy vapor of the kerosene (or other heavier petroleum product used) is then drawn through the zigzag passage 11, and since the cylinder-head has become considerably heated the heavy vapor is held long enough in the passage to become raised in temperature to cause its particles to become split up into relatively minute parts, or placed in a true gaseous condition, which, when the valves 13 and 16 are a rnate-l}? moved to permit its transmission to the combustion-chamber 3, moves into said chamber in a consistency much like that of the vaporous gas of the lighter hydrocarbons, there to be ignited and completely consumed in the usual Way. The alternated spaced ribs in the gas-producer chamber 9 therefore force the vapor through a longer channel and communicate thereto heat from their multiplied surfaces, by both conduction and radiation. I

In Fig. is illustrated a slightly varied ,type of my invention, in which the .gas-' the chamber 24 is arranged about a spiral wall 26. The said wall, as also its continuation Wall 24, has L-shaped baffling projections 28 alternated with like projections 27 in such a fashion that they extend between each other to leave openings in their ends to produce a zigzag passage. The kerosene vapor introduced into the inner end 30 of the passage 29 is forced to flow to the passage 25 the full length past the projections 27 and 28, which, however, do not prevent the free movement of the vapor, being arranged with their outer angles toward the flow of the current. The vapor is thus in a similar manner heated sufiiciently while held in said long passage to be broken into gaseous molecules for complete combustion without partialcondensation in the combustionchamber.

I do not wish, however, to be understood as confining myself strictly 'to the forms specifically shown herein, for it is obvious that many other specific forms may be made which will come within the general scope and principle of my invention.

What I claim as new, and desire to secure by Letters Patent, is:

1. A removable gasifying cylinder-head for an internal-combustion engine contain: ing a gasifying chamber in communication with a carbureter, and a reserve-supply chamber, the former being in communication with the latter chamber by means of a valve-controlled port, and the latter chamher being in communication with the combustion-chamber of the engine by means of a valve-controlled port, the valves in said 'ports being adapted to work alternately, to

permit a'reserve supply of heated gas to be stored in said supply-chamber and prevent its escape therefrom back into the gasifying chamber.

2. A removable gasifying cylinder-head for an internal-combustion engine, containing a gasifying chamber provided with projections of its inner walls into its interior to form a convoluted passage therein, and having a communication with the carbureter, said cylinder-head also containing a reservesupply chamber in communication with said gasifying chamber by means of a valve-controlled port, and also being in communication with the combustion-chamber of the engine by means of a valve-controlled port, the valve in the latter port being adapted for opening alternately with the opening of the former .valve, to secure a charge of gas in thelatter chamber and prevent its back movement into the gasifying chamber.
